, the Airbus A380 passenger aircraft that still maintains passenger record so far, can carry 853 people in the full economy class layout!
The weight of different types of aircraft also varies greatly, such as the Cessna 172 Skyhawk used by students who have just learned to fly, and the single-shot four-seater trainer . It has a wingspan of 11 meters and a height of 2.72 meters, and can accommodate 1 pilot and 3 passengers. Its empty weight is only 767 kg and its gross weight is 1111 kg. It is not as heavy as a Santana car (1160 kg.)
Next, introduce a dual-hair general-purpose aircraft - Beechcraft King Air.
This twin turboprop is obviously much bigger and heavier. As a general-purpose commuter aircraft, it can carry 1 to 2 pilots and up to 13 passengers. It is 12.17 meters long, has a wingspan of 14 meters, a height of 4.7, and has an empty weight of 3.2 tons, with a maximum take-off weight of 5.3 tons. This is equivalent to two equipped with V12-engine Rolls-Royce Phantom (2.6 tons)!
has the first two general aviation aircraft as the foundation, and I believe everyone should have a preliminary perception, but the aircraft has several different types of weights.
1. Maximum taxi weight: the heaviest weight of the aircraft. (There is still a difference between the maximum take-off weight and the maximum taxi weight.) In other words, even if the weight of the aircraft on the apron exceeds the maximum take-off weight, you don’t have to worry about it, just consume some fuel.
is calculated as the Airbus A380 passenger aircraft with the largest passenger capacity in the world. Its maximum taxiing weight is 562 tons! The weight of 484 Santanas or 216 Rolls-Royce Phantoms.
2, Maximum Takeoff Weight (MTOW abbreviated as MTOW): Due to design or operational limitations, the maximum weight that can meet the strength and capacity of the aircraft at the same time. It includes the sum of the fuselage, fuel, cargo and member weights. The pilot needs to calculate the takeoff speed required by the aircraft and ensure that the total weight remains below the maximum takeoff weight. Maximum takeoff weight is one of the three designed weight limits for the aircraft, and others include maximum fuel-free weight and maximum landing weight.
For example, when the passenger plane is preparing to take off, the engine fails and the emergency brake must be braked to stop the takeoff procedure, which can also ensure the maximum weight of safe stopping without damaging the aircraft.
In order to maintain safety and redundancy, passenger aircraft manufacturers sometimes deliberately lower the maximum take-off weight value. The maximum takeoff weight of
A380 is 560 tons.
In addition, environmental factors will also affect the maximum permitted takeoff weight of the aircraft. Including airport altitude, temperature, runway length, runway condition and obstacles.
3. Maximum landing weight: This weight is not only the weight that the aircraft can guarantee safe landing in structure, but also the weight that the aircraft can guarantee smooth climbing when it stops landing and resumes and encounters a transmitter failure. This is also the maximum weight of the aircraft's performance. The maximum landing weight of
A380 is 386 tons.
4. Maximum fuel-free weight: In addition to fuel, the passenger plane can carry the maximum cargo capacity of passengers and cargo. As the range continues, the fuel in the wings will gradually decrease, and the gravity of the aircraft will also decrease, but the pressure at the wing root will gradually increase and reach the maximum before fuel consumption. Under this premise, the strength of the wing must also be ensured to be undestroyed and the maximum weight is carried. The maximum fuel-free weight of
A380 is 361 tons.
